Abstract: 122,926. British Thomson - Houston Co., and Ash, J. J. Feb. 14, 1918. Systems for continuouscurrent motors only. - in systems where motors are started and stopped frequently, as when driving air - compressors, pumps, pneumatic riveting and drilling tools, a device affected by the temperature of the resistance or by the change in resistance due to temperature variations closes a controlling-circuit to shortcircuit the resistance while maintaining the motor circuit closed. In the arrangement shown, the armature 1 of the motor has a starting-resistance 3 controlled by contactors 4, 5 with actuating-coils 24, 26 controlled by an auxiliary contactor 16 operated when the switch 11 is closed. A pressure governor 8 controls the automatic starting and stopping mechanism when the air pressure falls or rises beyond predetermined limits. The actuating- circuit of the unloading-relay 28 includes the interlock 27 on the resistance contactor 5 and the contactor 20 coupled mechanically to the contactor 16. A thermostatic device 7 influenced by the temperature of the resistance 3 has an arm working between fixed contacts 29, 42. When the resistance is heated to a dangerous degree, the arm engages the contact 29 and completes the circuit of the actuating-coil 32 of the contactor 33..This closes a controlling-circuit for the contactors 4, 5 and the interlock 36 closes a maintaining-circuit, so that the motor continues to run, independently of the contactors 16, 20, so long as the temperature of the resistance is above a predetermined value. With the arm of the thermostat engaging the contact 42, a shunt circuit around the coil 32 is completed and the contactor 33 is opened.
